Entity-Relationship modeling in the Database management system is a technique used to determine the graphical relationship between the entities(entity is an abstract about which we want to store the information in our database). It is used by Software companies to design and present the database model for there clients.It enables to revise and make corrections to the model as many times as possible without wasting money ,moreover it helps to create an efficient physical database design which meets the clients requirements.

  E-R modeling is very important for the programmers to build extraordinary web or mobile app that requires database to just store data add by the admin .Adopting this method helps the programmers achieve great success with there application.It is a Top Down Approach.

Normalization is a bottom up approach ,where the rough table is gone through the refinement process to make it efficient,so that it enables Insert,Update,Delete operations for database and reduces duplicate data.It is used to create a database for online applications where end user can perform Insert,Update,Delete actions.
